add gsm0808_cell_id_list_add() to combine two cell identifier lists
This will be used by the upcoming neighbor_ident API in osmo-bsc, where the vty
interface allows composing neihbor BSS cell identifier lists, and we want to
allow adding individual items from individual user commands.
It will also be useful to accumulate cell identifiers in case a subscriber sees
multiple alternative cells from a neighboring BSS, and we want to pass these on
to the MSC in a Handover Required.
